The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As depicted in figs. 1 and 2, described weld fumes ventilated purification apparatus:
Second level grid clarifier 9 is set between described deashing chamber 8 and exhaust duct 4 again, passes through the air of two-step purification like this, reach the national environmental protection emission standards fully, can directly be thrown in the atmosphere.
A by-pass valve control 12 is set between described second level grid clarifier 9 and exhaust duct 4 again, both be arranged on the porch of exhaust duct 4, general this by-pass valve control 12 is selected the electronic leafy by-pass valve control of splitting for use, under normal operating conditions, this by-pass valve control 12 is an open mode, after quitting work, by-pass valve control 12 can be closed, avoid extraneous foreign material to enter in the clean room 3 by exhaust duct 4.
A silencing apparatus 10 is installed on described exhaust duct 4.
Because welding fume is along with air flows together, so in order more quickly the weld fumes in the factory building to be got rid of, increase the speed that air flows in the factory building, in described weld fumes ventilated purification apparatus, also be provided with an air-supply arrangement 13, it is the housing that a centrifugal blower 15 is equipped with in an inside, be positioned over the outdoor of factory building, the outlet of described air-supply arrangement 13 connects air supply duct 14, on the wall around the air outlet of air supply duct 14 evenly is arranged in the factory building, because the wind-warm syndrome degree that air supply duct 14 send is relatively low, so air outlet is arranged on the position near ground, more helps air circulation.In the porch of described air-supply arrangement 13 air cleaner 17 is set, be used to filter the air that enters from the external world, the air that guarantees to send in the factory building all is fresh clean, and the air rate of ventilation can reach 5-6 time/hour, the assurance room air is fresh, and sanitary index is up to state standards.
